But a faulty engine coolant temperature (ECT) sensor can cause havoc on an engine or its related systems. A coolant temperature sensor is confined to the engine of a vehicle. We actually do not know what the -08 reading is. A good example of a coolant temperature switch would be the device controlling the dash board coolant temperature light (aka "idiot light"). I have previously posted on how to get air out of the engine coolant loop after replacing coolant. I'm covering for you. Most coolant. If your temp gage does not work, this is probably the reason why. If the air was not purged out of the coolant system, that will cause DTC P1116. Once again, drain the cooling system, collecting all waste fluid. if the coolant temp sensor is broken you will stay in open loop (cold start) and should run rich. The engine coolant temperature sensor resistance changes in response to engine coolant temperature. The thermo fan switch responds to changes in engine coolant temperature, providing circuit switching during a predetermined temperature range allowing fan operation.
